11% of turnover is pretty damn good, however, sometimes the orderbook here is so thin and it can barely sustain a trade that's > 1.5BTC or above...
The true cost of turning it over one time is actually higher because your market order eats up all the levels on the orderbook.
Good share!
I looked again - there is significant amount periodically. But, so as not to bring down the market price, it is possible to put multiple orders.
